This 4g bag of cartridge filler is enough to refill
up to 80 x Joye 510 cartridges!
This is the same filler found in DSE801, DSE901 and Joye 510 cartridges. Refill your cartridges instead of throwing them out.
Refilling Tips:
*Stuffing the cartridge too densely will cause poor absorption and cartridge will not wick properly.
*Pack into cartridge loosely. Test by adding a few drops. Add more filler if needed. If liquid spills out of the cartridge when it is flipped upside down, then more fill is needed.
*Always rinse and clean cartridges before refilling with new filler.
